This printed Constitution of the Minnesota Academy of Science is from around 1937. It is very similar to the 1933 Constitution but has removed the associate membership category; the By-Laws set the annual dues as "one dollar for each member." The election process for members is also different, requiring nomination by a member, recommendation by the Council, and a two-thirds vote of the organization, at which point "he shall be duly elected."
